The death of Nancy Kerrigan‘s father, Daniel, has been ruled a homicide.

The Medical Examiner determined that the cause of death was “cardiac dysrhythmia following a physical altercation with neck compression causing injury to the neck in the form of a cartilage fracture to the larynx area, in a person with hypertensive and atherosclerotic cardiovascular heart disease.

According to local authorities, “As a result of these conclusions of the Medical Examiner, the investigation into Daniel Kerrigan’s death, and whether any charges in connection with his death are appropriate, remains ongoing.”
